How the function package-installed-p should behave on emacs startup if
some package is already installed? It seems that it returns nil for
installed package on emacs startup.

Here is the full .emacs file (used for this test):

(require 'package)
(message "**** auto-complete is installed: %s ****" (package-installed-p
'auto-complete))

auto-complete package is installed for this moument, but during emacs
sturtup *Messages* buffer shows:

**** auto-complete is installed: nil ****

But after sturtup the evaluation of the expression

(message "**** auto-complete is installed: %s ****" (package-installed-p
'auto-complete))

returns:

**** auto-complete is installed: t ****

But how it is possible to install just not already installed packages on
startup. For this moument all packages are re-downloaded and reinstalled
for me during every emacs startup.
